寻找目标数的最小值,是不会越界的因为最后剩两个的时候循环里还有一次l+1,然后l就自动指向了目标值。一般都是r=mid...540. Single Element in a Sorted Array 540. Single Element in a Sorted Array 题目大意: 给你一个由小到大排好序的数组,里面只有一个数出现了一次,其他数都出现了两次,要求找出那个...
Given an array of integersnumssorted in ascending order, find the starting and ending position of a giventargetvalue. Your algorithm's runtime complexity must be in the order ofO(logn). If the target is not found in the array, return[-1, -1]. Example 1: Input: nums = [5,7,7,8,...
总结:Using two pointers again, first is to use binary search to find the first target, then make l = mid and r = mid, expand in two directions and break. Then l is the first index, r is the last index. Including the situations that nums.length == 0/1 or only 1 target in arra...
1. Problem Descriptions:Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value.If target is not found in the array, return [-1…

print maximum first k element c=(a[i] * b[j]) ( 1<=i,j<=n) For example: input: n=3 k=3 a={1,2,3} b={4,5,6} Correct output: 6 12 18 I'm trying to solve problem like this , but i don't have any idea for getting "AC" , so i need some helps , thank everybo...
Finding the first repeated element in an arrayWe have to use two loops (nested loops), let check first element to other elements, if same element found, get the index and break the loop, run the loop until same element is not found or end of the elements....
Given an unsorted integer array, find the first missing positive integer. For example, Given[1,2,0]return3, and[3,4,-1,1]return2. Your algorithm should run inO(n) time and uses constant space. 对于正数A[i],我们希望它能被放在第i个位置上,这样子当我们找到A[i] != i时,我们就找到了...
Given a sorted array of integers, find the starting and ending position of a given target value. Your algorithm's runtime complexity must be in the order of O(log n).If the targetisnot foundinthe array,return[-1, -1]. For example, ...
